A simple multi-piece manually operated kitchen tool intended for use in a home or small kitchen wherein this tool is used to form baking liner material into a formed baking liner having flat bottom and fluted sidewalls. The perimeter of the kitchen tool may be designed to form a traditional circular liner as for cupcakes or alternately a rectangle or some other geometric or non-geometric shape such as semi-circle, rectangle, ellipse, star, crescent, sun, heart, etc.

Method and apparatus for producing hangers and similar devices. In some examples, a method includes wetting a flat layer of paper material to increase humidity percentage at room temperature; leaving said layer of paper material to rest for a predetermined period of time; cutting said flat layer of paper material to define an appropriate shape for the hanger; carrying out a knurling operation on at least one portion of the flat layer of paper material so that at least one concave area is realized; forming the flat layer of paper material by introducing the flat layer of paper material between a mould and a counter-mould and subsequently through pressing; and carrying out a stabilisation operation of the hanger to reduce the humidity percentage.

A method for manufacturing three-dimensional products with at least one inclined product portion made of a fiber-containing material using at least one forming tool and a forming tool are described. Vibrations are introduced via a device and this results in an improved compression of fiber-containing material in the region of inclined portions.

A method and system for edge-forming cellulose products from an air-formed cellulose blank structure. The system comprises a first mould part having an edge-forming device with a protruding element configured for compacting and separating fibres of the cellulose blank structure and a second mould part arranged for cooperating with each other. The edge-forming device is movably arranged in relation to a base structure of the first mould part, and is adapted for interacting with a pressure member arranged in the base structure. The method includes the steps: providing the air-formed cellulose blank structure, and forming a compacted edge structure of the cellulose products by separating fibres of the cellulose blank structure with the protruding element, applying an edge-forming temperature, and compacting the cellulose blank structure by applying an edge-forming pressure onto the cellulose blank structure between the protruding element and the second mould part.

Structures including a curved corrugated wall fabricated from a plurality of layers formed of one or more shaped strips and methods of forming the structures are described. A shaped strip used in the fabrication includes a variable profile across the width of the strip with a first edge of a strip defining a series of cell profiles of a first geometric shape and a second, opposite edge of the strip defining a series of cell profiles of a second, different geometric shape, with each cell transitioning from the first profile to the second profile across the width of the strip. The geometry of the cell profiles at either end of each cell can be designed with respect to one another to allow for radial orientation of the strip about an axis with little or no deformation or stress on the strip edges.

In one embodiment, an apparatus and a method of manufacturing a paperboard tray therewith is provided. In particular, a hub is configured to rotate about a shaft. On the hub, a plurality of first molds are formed in the hub. Conversely, a plurality of second molds are each disposed above each of the plurality of first molds respectively and rotate above the first molds. In this configuration, the plurality of second molds are configured to move in unison with the plurality of first molds as the hub and second molds rotate and to move orthogonally towards and then away from the first molds as the second molds rotate.
